I would describe my problem as DBCP is not reusing database connections when it should but it instead creates a new one, until the SQL server has too many connections (or your DBCP hits upper parameter limits). With TC and MySQL I can confirm this by logging my database handle close and watching what happens with SHOW PROCESSLIST sql command on the server. Each request needs 1 database connection and the logging should confirm it returns (releases) the connection back to DBCP pool. I have followed this path with the debugger and got inside DBCP to prove the release takes place. I had put down the problem and just configured up my DBCP parameters to expire old connections as fast as possible and up the maximum limits. This wont work for me in production, maybe I switch to C3P0 connection pooling at that time. Its just so difficult to help out and nail the problem with TCs refactored and repackaged DBCP, I would very much appreciate an SDK version of the full TC package that includes all source in the JARs. I am doing a CVS build.xml now, but I think this will be for 5.5.12, I just need to work out how to fix the version for a 5.5.9 release and compare the two trees to maybe try and nail this one, or at least confirm the blame here is with DBCP. -- Darryl L.

I started getting exceptions saying no connections were available on my JDBC datasource (org.gjt.mm.mysql.Driver). The pool was definitely large enough to handle the load. So it appears that I'm not freeing the all the connections as I should. I noticed that I did not have the 'removeAbandoned' flag set on the Resource tag. Changing that has apparently fixed the out of connections problem. But I really want to clean up the code and fix it the right way. I've got the close() statements in place. But obviously, I'm missing some of them somewhere. Is there any process for logging/tracking allocating and freeing connections (and absence thereof.), available connections, etc? Or are there any methods I can call to give me this type of debug info? What's the recommended way to debug this? Thanks.

RE: Flexible way of defining application variables in text format?
I use a properties file stored in the WEB-INF directory. Modifying the web.xml is too error prone. Using another XML file is a lot harder than a properties file. Just use the servlet context getResourceAsStream(), and pass that to the properties.load() method.

My webapp needs some application string variables for configuration. For the moment, I hard-code them as class static properties and compiled. But I'd like to know if there's any method to define such variables in a text file, something like the global.asa in ASP where we could simply write something like this withing the application_onstart subroutine: application(myvar) = my value I like them to be withing text file because if even there's a need to change config, I'd like to just launch a text editor, edit it and start again! I don't want to install Eclipse or other IDE in deployment server just in case we need to change some parameter and have to compile everything. This is very inconvenient, non professional and stupid. And the client would probably not appreciate this. OK, I know I could write a wrapper function to parse that text file and assign the correct values, but is there a simpler way?

RE: Order of WebApp Loading
Its not deterministic. Save yourself a lot of time, and don't complain about it and ask it to be changed. You need to re-think your logic so there is not a dependency. A pretty obvious solution would be to have either application check to see if the database is started, and if not start the database.

RE: The process tomcat {pid 1488.0000 } is leaking handles
I have a web application that I host for our customers. Right now we are
running about 60 virtual hosts with tens of thousands of hits per day. I've
also run stress tests using Jmeter where literally millions of requests are
generated. I have never observed a resource leak.
This is a common topic in the forum. In almost every instance, it is the
application that is leaking resources.
Developers should run findbugs:

And PMD

Re: Advice for Hosting Many Individual Webapps?
To re-start tomcat, I start a second instance running on a different port and after the second instance is running, change the port forwarding to activate it. If so is there an advantage to doing that over clustering? It's a simple configuration that only requires one machine. As nice as clustering sounds, it's not as useful as people think. Two areas where clustering won't work: Application upgrade that requires database structure change. Application upgrade that mades the serialized version of the properties incompatible from one version to the next. Another problem for me with clustering is that it seems to require an external director that would balance the requests across the host. If this is mod_jk and Apache, that's pretty ungainly if you are running a hosting operation with 200 virtual hosts. If it's an external load balance, that's a third piece of hardware. On Thursday 18 August 2005 10:15, Brian Cook wrote: Sorry still not following. If Tomcat is being restarted how do you not have start up time?

The technique I use is this: Run the HTTP connector on port 8080. Forward port 80 to port 8080. To re-start the system: edit the server.xml and run the HTTP connector on port 7080 Change the shutdown port to 8006 Start tomcat, and wait till it comes up. Re-run the firewall script to forward port 80 to port 7080. Stop the instance running on port 7080. The downside is that any active sessions get bounced and have to re-login.

Hello, We are finding outselves hosting more and more individual webapps, all running on Tomcat 5.5.9 w/ JDK 1.5. Each of these webapps is developed and deployed on a separate schedule, and the number and frequency of app deployments is increasing. The frequency is so much that the uptime of all of our applications is affected as we continually take down Tomcat servers in production to deploy a new application (or new version of the application). Because hot deploy does not work (the old favorite OOM error w/ too many redeploys), we bounce the Tomcat server for every redeploy. To avoid taking down all of our applications when we need to redeploy a single app, we've begun to deploy each application to their own Tomcat instance. All of these instances are fronted by a single Apache server handling vhosts, logging, etc. We're just curious how common this setup really is. We know we are in an uncommon position, with so many webapps (approaching 20, and growing very fast). We don't want to put all our eggs in one basket, so to speak, so we've begun to split out individual tomcat instances. Anyone else have to handle numerous webapps, with frequent deploys, and have to keep uptime for all apps as high as possible? We hesitate to put all webapps in one tomcat, because to deploy one app means we have to take down all of our apps. This is becoming unacceptable. (not to mention that a memory leak in one app will bring down all the apps living in that tomcat instance) Any tips or tricks would be really appreciated. Or pointers to previous material (I've found some, but nothing that jumped out at me).

RE: Tomcat and the HttpServletRequest Object
Even if I were to write this as an enhancement, I can tell you from past
experience it would be rejected out of hand by the committers.
In your particular case, the tool you were using before used something like
a Vector or ArrayList to hold the parameter name/value pairs. Tomcat is
almost certainly using a HashMap of some sort. Any deterministic
implementation is going to be slower than the current random access
implementation. Committers will savage any submission that appears slower
and the person submitting it. No thanks, I'm not going there.
Even if Tomcat were to work in the manner desired, there's nothing that says
that every browser is going to submit the form elements in their order of
definition. You really need to abandon this idea and make your application
more robust.
You remind me of people who do SQL database development. They don't specify
an ORDER BY clause on their statements, but it always came back in the order
they wanted. Then one day, they upgraded versions of the database or the
query optimizer decided to take a different path, and all of a sudden the
results are coming out of order. Much wailing and attempted reporting of
bugs ensues... The truth is in SQL, that if you don't specify an ORDER BY
clause, the database can return the results in any order it likes.
Taking advantage of an implementation specific behavior is natural, but it
can lead (as you have found out) to non-portable code. The final arbiter is
the specification, and if the specification doesn't describe the behavior,
you can't say anything about it.

RE: tomcat and active directory
It looks like you are configured for anonymous bind.
By default, the AD LDAP implementation does not allow anonymous bind. You
have two ways of handling this:
1. Configure your AD tree to allow anonymous bind. Essentially, you will
need to create an ACL against the appropriate object (container) in the
tree.
2. Create a low powered user that has read access to the directory tree
and configure the realm to bind as that user..

RE: tomcat and active directory
In order to query the LDAP tree, you have to bind to it. Binding requires
that anonymous bind be enabled, or that you bind with a user id and
password. This is just how LDAP works.
The information that I sent you was information I learned while creating an
LDAP authentication module for our software.

Got a bounce the first time... -- Forwarded message -- From: George Finklang [EMAIL PROTECTED] Date: Jul 15, 2005 10:59 AM Subject: Re: Any kind of Request Recorder/Player available? To: Tomcat Users List tomcat-user@jakarta.apache.org netbeans.org has a http monitor module that can record and playback of http requests, plugged into netbeans' web development framework. I think you could just download just that module and manually install it into your tomcat, and use the UI from netbeans to do the record/playback. It actually can be installed into any newer application server that is up to date in its servlet support. go to http://monitor.netbeans.org for more details --George On 7/15/05, Frank W.

I don't know of anything that exists, although I'm quite certain something does. :) I can however think it through, and its probably not a huge chore to build... As you mentioned, a filter would probably do the trick nicely... if we assume your app only deals in POSTs and GETs of basic user input (because things like multiparts and such would complicate matters a bit), then it's really just a simple filter that iterates over all parameters and stores them. Just a simple CSV file of name=value pairs would suffice, with each line being a request. Then it should be a simple matter to write a Java app using the standard JDK classes to run through that CSV file and make the requests with the parameters you recorded. -- Frank W. Zammetti Founder and Chief Software Architect Omnytex Technologies http://www.omnytex.com On Fri, July 15, 2005 1:28 pm, Will Hartung said: With Apache JMeter, they have a proxy that you can use to record a session with the server, and you can then use that as a basis for load testing and what not. What I'm looking for is something similar, but something that I can ideally place in Tomcat (as a Valve perhaps, or a Servlet filter). Basically, something that records the entire incoming request and then stores it out in a format that can later be played back by another tool. The problem is that we have a server than has a production memory leak, and the profilers are basically worthless in production. But if I can place a logger and record a days traffic, and then replay it against a test server (with all the monitoring etc.), then I can more easily reproduce the problem without heavily impacting performance of the production server.

Re: Trying to configure apache, tomcat and mod_jk
Hey Matthew, I'm no expert, but I can tell you what I did to get it running. I'm running Apache 2.0 on Fedora Core 4. I basically ended up just rolling back my versions to get things to work. I rolled back to Tomcat 5.0.28 with mod_jk 1.2.10. It's true. The documentation on the web is out of date and very confusing. I set things up considerably different, though. For example, I was just trying to serve jsp's from the $CATALINA_HOME\webapps directory. I'm not entirely sure, but I think the JkMount directive only points to that directory. It looks like you're defining more workers in your workers.properties than you're actually using in httpd.conf. I don't think you need the ajp12 worker. Another thing is that you have not defined a JkShmFile (a shared memory file). This is required for connectors 1.2.10 and later (although 1.2.13 might set one up on its own). Here's a link to the relevant lines in my config files. I got this working this weekend, so you can be sure they're fresh. http://ill-conditioned.stanford.edu/JSPWiki/Wiki.jsp?page=Fedora If the wiki link doesn't work, then you know I'm still having problems. :) Hope this helps, Paul Quoting Matthew Strawbridge [EMAIL PROTECTED]: Hi After spending several days trying to set this up from the documentation, I've finally decided I need some expert help. I have a server set up with several domains sharing an IP address. I want to be able to have JSP files in amongst my static files, and have apache serve the static ones and to forward the requests for *.jsp to tomcat using mod_jk. At present: http://www.philoxenic.com:8080/test.jsp correctly serves up /home/httpd/vhosts/philoxenic.com/jsp/test.jsp through tomcat. (I would rather have these files in ../httpdocs/, but thought it might be easier if apache couldn't find the files itself). http://www.philoxenic.com/test.jsp comes up with a 'Not Found' error. This is what I want to get working. If I copy test.jsp from 'jsp' to 'httpdocs' then http://www.philoxenic.com/test.jsp serves it up as plain HTML (i.e. bypassing Tomcat). Please can someone point me in the right direction. To get this far I've had to recompile apache, compile tomcat and mod_jk, and think I have been going round in circles following out-of-date documents on the Web. I feel I'm close, but perhaps can't see the wood for the trees.

Jk's shared memory file - fixed? bug?
Ok, here's what happened. I'm running Apace 2.0 on Fedora Core 4, connecting
to Tomcat 5.0.28 with Jk 1.2.10. In my /etc/httpd/conf/httpd.conf, I had:
#Jk stuff
LoadModule jk_module /usr/lib/httpd/modules/mod_jk.so
JkWorkersFile /etc/httpd/conf/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkLogStampFormat [%a %b %d %H:%M:%S %Y]
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkMount /jsp-examples/* ajp13w
JkMount /JSPWiki/* ajp13w
JkShmFile /etc/httpd/logs/jk-runtime-status
In /etc/httpd/conf/workers.properties, I had:
worker.list=wlb,jkstatus,ajp13w
worker.ajp13w.type=ajp13
worker.ajp13w.host=localhost
worker.ajp13w.port=8009
worker.wlb.type=lb
worker.wlb.balance_workers=ajp13w
worker.jkstatus.type=status
In /usr/share/tomcat5/conf/server.xml, I had
Listener
className=org.apache.jk.config.ApacheConfig
configHome=/usr/share/tomcat5
modJk=/usr/lib/httpd/modules/mod_jk.so
jkWorker=ajp13w
forwardAll=False
jkLog=/etc/httpd/logs/mod_jk.log
jkDebug=debug
noRoot=False
workersConfig=/etc/httpd/conf/workers.properties/
Connector port=8009
enableLookups=false redirectPort=8443 debug=0
protocol=AJP/1.3 /
Everything was working fine until the file /etc/httpd/logs/jk-runtime-status
reached the default JkShmSize limit of 64k. Once that happened, everything
died. I started getting errors in mod_jk.log like:
[error] init_jk::mod_jk.c (2347): Initializing
shm:/etc/httpd/logs/jk-runtime-status errno=13
errno=13 is typically a permission denied error, but my permissions were set
appropriately. I tried deleting the contents of
/etc/httpd/logs/jk-runtime-status to get below the size limit, but that
didn't help anything. I tried creating a new file /etc/httpd/logs/jk.shm
and pointing my config file there, but no success. I didn't get things
working again until I recompiled my mod_jk.so and reinstalled it. I checked
out the code in jk_shm.c that was giving me an error:
jk_shmem.hdr = (jk_shm_header_t *)calloc(1, jk_shmem.size);
if (!jk_shmem.hdr) {
JK_TRACE_EXIT(l);
return -1;
}
So, devs, why was this breaking? I've now set JkShmSize to 10M. But will it
break again once jk.shm reaches 10M?
Anybody out there?

memory issues with live redeploy
Working with a couple different tomcat 5.0.X versions, I'm having issues with tomcat's memory footprint increasing when I live redeploy. I do this 2 or 3 times and the server runs out of memory, though normally it can run for weeks without problem. I can't seem to find direct references to this in the online docs. Is it jsp compilation or session state usage (or other things I can affect)? Or is it just a known limitation in the container? --George - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I've had pretty much exclusive use of the Tomcat server during development, but when I started allowing other users on it, I stumbled on some problems. Basically what happens, when user A submits the form, and then 2 seconds later user B submits the same form. User A stops getting results, and User B receives the output for his request as well as the end of User A's request. User A is on a different computer than B and both have different session ID's. I'm sure this is a configuration error on my part, but would appreciate a direction on where to look. PS - I create a session if it doesn't exist, and store the username and DB connection in it.

It's almost certainly your application. I would start with findbugs http://findbugs.sourceforge.net/ And if it doesn't help you sort it out, look at an application profiler. I run about 40 virtual hosts, with a fairly complex calendar app, that gets 10s of thousands of hits per day, on a PIII 500, and the utilization is around 5-10% during the day.

RE: HttpSessionListener
Hi Christopher,
I think I've fixed the problem. I did two things
1) I renamed the SessionCounter to MyCounter
2) Somehow I had commented out the
HttpSession session = request.getSession(true);
Once I had a session started everything worked (including the Tomcat Manager
sessions). I am still baffled as to why it continued to work on the
developer server after the session was commented out, but assume it was
cached somehow. I finally noticed it after rebooting the system and finding
the developer server having the same problem.
A little humbling, but a happy ending. Thanks for your help!

Yes that is my thought, too. There is a SessionListener initialized but
apparently not yours. You should put a log statement into the
constructor of your listener and make sure.

If not, you should try to do it in the same way on the devel box as you
do on the prod box and look if the problem appears on the prod box, too.
Another idea: the name (com.test.SessionCounter) of your listenere is
not very unique. Maybe there is a conflcit with an existing class in
Tomcats shared or common folder on the production system. Are there any
other applications installed on the production tomcat?
I also just noticed that the Tomcat WebApp Manager is showing only 0's for

That is really strange. Are you sure that you are hitting the production

I suspect that the Listener class is not found on the production server.
You should check your deployment. Are you deplyoing via WAR files in
both cases?
Yea, I would make sure that your listener is even being instantiated.
Tomcat is pretty quiet with things like Listners, it doens't write error or
output where you typically see it for you application.
Check all of your logs to make sure the class is loading and starting up
correctly.

RE: tomcat freezes when accessing db after several queries
Look for something like this:
Try {
statement.execUupdate(some statement);
} catch (SQLException se){
}
Make sure that the catch has:
conn.rollback();
In JDBC, a failed update leaves the underlying record locked until it is
rolled back.

Subject: tomcat freezes when accessing db after several queries
Hi all,
I've encountered a rather strange error that I need some help
getting to the bottom of. Recently I lost the hard drive on
one of my tomcat
application servers. I've since reinstalled and set everything on the
effected machine to mirror the configuration of my other app
servers (which
are working fine). However, now when I access the webapp on
this server
tomcat seems to freeze (like it's waiting for something) after several
queries to the database are executed. After this happens I am
unable to
shutdown tomcat without finding the process number and
terminating it using
kill -9 as shutdown.sh fails to halt execution. This seems
pretty strange to
me since one, the problem occurs without any errors appearing in
catalina.out or the localhost_log files and two the webapp is
able to access
the DB with several queries before it encounters any
problems. Does anyone
have any ideas what may be causing this to happen?
Thanks in advance,
Larry

RE: Date parsing
Well because of the ambiguities you have to have some expectation of what
format the date will be in.
What date is 05/12/2005? In the US its May 12th. In Britain it's December
5th. You have to have some expectation and validate against it.
The software is designed to use a Locale as an aid to parsing to set up the
expectation. In our software, we use the browser's accept-language to
retreive a locale.
The class as designed doesn't handle times. It's strictly a date class. Im
thinking about writing a date/time class, but haven't yet.

However what I am looking for is some class that can handle a
date/time
string in many different formats and return a date/time object back to

not. This probably means that locale change is required.
Also I tried
3/1/2005 11:45 am, and that failed as well. I am assuming
this code was

RE: Question for Tomcat Developers - How to Plug In Encryption for JDBC passwords
Your argument about short duration attacks is optimistic at best. Most systems are so poorly secured and monitored, that breakins aren't detected anywhere near that quickly. Let's face reality here. The only safe way to hide the JDBC information is to have the SECRET (encryption password) not available on the server. Any other method is not secure, it is just obfuscation. The tomcat developers quite rightly are refusing to implement any kind of scheme that isn't correct. Look at the startup sequence for Apache using SSL certificates. You have to type in the password for the private key. If you really want to do this, then you will need to have your application startup have a method that permits an operator to enter in the password for the JDBC information at startup. This means that every time your application is re-started, an operator will have to re-enter the information before the application can run. I'd really suggest you purchase and read Bruce Schneir's book Applied Cryptography. Plan on spending a several evenings with it. Just for grins, here's a link to a Javadoc for a crypto system that I designed for a shopping cart. The overriding design goal was to ensure that credit card data would not be revealed even if the database were compromised. I don't see any shortcomings in it, but I haven't opened it up to public review before. http://www.mhsoftware.com/~gsexton/Crypto.html George Sexton MH Software, Inc. http://www.mhsoftware.com/ Voice: 303 438 9585 -Original Message- From: Edmon Begoli [mailto:[EMAIL PROTECTED] Sent: Sunday, February 27, 2005 1:15 AM To: Tomcat Users List Subject: Re: Question for Tomcat Developers - How to Plug In Encryption for JDBC passwords Please do not start the flame war.

RE: Running heavily loaded tomcat sites.
You are really just starting document the issues necessary for running a high volume site. The URL http://www.mhsoftware.com/resources/top10asp.html Has some things that are IIS specific, but also apply to Tomcat applications: Specifically: Store as little as possible on the session. I'm working on an app right now, where the author decided storing the db connection on the session was the way to go. Watch contention. Use an automated code analysis tool like PMD or Findbugs to eliminate bad and redundant code. PMD will detect things like string concatenation in loops, using string concatenation in StringBuffer.append() methods, and other non-optimal techniques. Stress test using a tool like Jmeter.

RE: [OT]web development fee
I've got a package I plan on releasing under a BSD license. It needs some work, but it's pretty close. The only remaining major task is to port the reports from an old proprietary reporting application to Datavision. If you want to see a sample, go to: http://www.stargateschool.org/sgstore/ The sample is not quite in production, so if you want to try it out, use a Visa Card # of 4111 (4 followed by 15 1's). I'd appreciate any feedback. In many ways, it's very cool. Formats for the items are stored as HTML, and parsed out. Products can belong to multiple categories, and shopping by Manufacturer is supported. It does inventory, removing items from the store when the quantity on hand drops to 0. It also supports quantity pricing schedules as well as SKU Variants (vary on size, or color but not both). Support for Accessory SKU's that can be shown in the checkout or cart review screens. Orders are delivered to the fulfillment person via FAX, PDF or Encrypted PDF. A CC of the PDF without the card data can also be sent to an additional person. It should be portable across PostgreSQL, SQL Server, Oracle, Sybase, and DB2, but I've only tested PostgreSQL and SQL Server so far. I'll be the first to admit it could use some more features.

From my experience there are a couple of options you can pursue: 1) You could build the application from the ground up and charge an hourly rate. The rate will have to be agreed upon by you and the person contracting you. 2) You could develop the eCommerce application at your own cost and sell a license to it. In this case you would have more direct control over the features you build into it. Also, while this costs you more up front there is more possibility to recover the cost in selling multiple licenses. 3) You could purchase a license to an existing application and adapt it to meet your clients' needs. In this case you would likely charge a flat fee to recover your hard costs for the purchase and an hourly after that for any adaptations. In this case I personally would ask for the hard costs up front so as to not go to the expense and then have the client change his/her mind. Now about the way you asked your question, I'm not sure if the web application you have developed for your employer is an eCommerce application. In the event that it is eCommerce related you will likely use that as a base for whatever you build for your new client. In this case you should discuss with your employer how he feels about you building off of a code base that he has funded. It may be that you could work out an arrangement with your employer to accomplish option 3 above, and that your employer will give you a license at a significant savings to you. As far as contracts go, you should probably consult with a lawyer for that. Daniel - Original Message - From: epyonne

ChannelSocket is loosing connections
Hi, After investigating the problem we have reported earlier a little more, it looks like we have the following problem: Every now and then we get heaps of SocketExceptions in the logs on Tomcat, all in ChannelSocket.invoke() in jk.common.ChannelSocket.java. Then all TP-Processor threads are going into standby mode, ie. if I do a dump of all threads of the JVM, all Tomcat TP-Processor threads sit in the socketRead0() call waiting for mod_jk to send some subsequent data. But the mod_jk side of things looks different, it claims it is waiting for Tomcat to send back data for the current requests! I did a netstat -p then on the app servers and saw that mod_jk did indeed still have a socket connection to the Java processes. So, Tomcat/CoyoteConnector sits idle waiting for connections but in reality, the socket connections are stuck somewhere and not closed properly. Apache/mod_jk is waiting for Tomcat to write the response back to the user, but since the exception was thrown it is not going to do that. While reading the ChannelSocket.processConnection() code I came across a final and this comment: /* * Whatever happened to this connection (remote closed it, timeout, read error) * the socket SHOULD be closed, or we may be in situation where the webserver * will continue to think the socket is still open and will forward request * to tomcat without receiving ever a reply */ Well, this seem to be exactly our problem! I see from the code that it should closethe connection since a SocketException is thrown in this.invoke(recv, ep);, which should trigger the close call. But then, what is going wrong? Why is Tomcat and mod_jk getting out of sync with connections? I am puzzled. Please can anyone out there help?

Re: Problems wth Apache, mod_jk2 and Tomcat
David, Checking my log files, I can see that I get many of thoe lines in the generic apache error log: [...timestamp...] [error] child process xyzabc still did not exit, sending a SIGKILL I get at least 40 of these just after it starts running full. That does not look ok, does it? Lars David Smith wrote: Hmmm.. My assumption to your email was their was some kind of possible probing of your Apache server and/or a misbehaving client.

Re: JK2: mapping urls from Apache to Tomcat
Andrzej, If you are referring to rewriting URI's before hitting the app servers then we do this with mod_rewrite which executes before mod_jk. So fr example if we have to change a legacy URI to a new one then we do this with a rewrite rule before even mod_jk is called. Works great for us.

ISAPI and SSI w/ IIS
I have been playing with trying to server side include a URL that is in a context handled by the ISAPI redirector. This is on Windows Server 2003 with isapi_redirector2.dll version 2.0.4. The chain is something like this: URL /calendar/OutputCurrentWeek.html is in a context handled by the ISAPI Filter. Directly invoking this URL produces output. Attempting to invoke the URL via SSI as shown below fails: !-- #include virtual=/calendar/OutputCurrentWeek.html?calendar_id=2 -- I'm pretty sure that what is happening is the SSI handler is not passing the request through the ISAPI filter chain. I also tried something like: !-- #exec isa=/jakarta/isapi_redirector2.dll?/calendar/OutputCurrentWeek.html?calenda r_id=2 -- And !-- #exec cgi=/jakarta/isapi_redirector2.dll?/calendar/OutputCurrentWeek.html?calenda r_id=2 -- The last two trys generated 500 errors. Does anyone have any ideas on how I can do a server side include to a context URL? As a fallback, I can use some code to invoke the URL using a Microsoft.XMLHTTP control, and retrieving the body text. Any ideas are appreciated.

Re: HttpUrlConnection.getInputStream() returns empty
Hi David,
My environment is Tomcat 4.1.18 + Sun JDK 1.4. I do
not use JSP and in my case a servlet invokes a java
class.
Now I got solution to my problem. The issue was that
the InputStream.avaulable() was returning 0 even
through there is byates to read.
My old code for reading bytes from the stream was like
this..
InputStream is = ..
byte[] b = new byte[is.available()];
is.read(b);
I modified this to...
ArrayList lines = new ArrayList();
BufferedReader r = new BufferedReader
(new InputStreamReader(in));
String line = null;
while ( (line=r.readLine()) != null )
{
if (StringUtils.isNotEmpty(line))
{
lines.add(line.trim());
}
}
Now I am getting the contents from the stream.
From the JSSE Ref Guide:
Implementation Note: Due to the complexity of the SSL
and TLS protocols, it is difficult to predict whether
incoming bytes on a connection are handshake or
application data, and how that data might affect the
current connection state (even causing the process to
block). In the Sun JSSE implementation, the
available() method on the object obtained by
SSLSocket.getInputStream() returns a count of the
number of application data bytes successfully
decrypted from the SSL connection but not yet read by
the application.
Thanks,
George

Re: HttpUrlConnection.getInputStream() returns empty
Hi reynir,
I have made the changes as per you suggestion and I
am getting the response code as 200. But still the
inputstream returns empty, is.available() returns 0
bytes.
thanks,

hi,
you could maybe try somthing like the following :
try
{
String str_url = https://www.domain.com;;
URL urlid = new URL(str_url);
HttpsURLConnection conn =
(HttpsURLConnection)urlid.openConnection();
conn.setRequestMethod(GET);
conn.setDoOutput(false);
out.write(RESPONSECODE = +
conn.getResponseCode()+\nbr);
BufferedReader in1 = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
String line;
while ((line = in1.readLine()) != null)
out.write(line +\n);
}
catch (Exception e)
{
e.printStackTrace(System.out);
}
hope it helps
